DOC-120 and DOC-130 are elevator main boards for LG/SIGMA elevators. If it’s a single-unit operation, you can use DOC-131 as a replacement. However, if the elevator system involves two parallel units, both elevators must have their main boards replaced together—switching from DOC-120 to DOC-131. Otherwise, there may be issues during debugging.
